Do you know if the capacitors are OK
C201 2p C202 120p C209 6.8p C203 .01 C213 270 How about the reactance tube itself (6AN8)? The reactance tube works by amplifying the effect of C201 by the variable gain of the tube. You can check if the oscillator can be pulled by putting, I don't know for sure, but maybe 100pF, from the plate of the reactance tube to ground. If this can pull the oscillator to a lower frequency, and the reactance tube cannot, the problem is in the reactance tube circuit. |
